Patent DE-19621794-A1 (DE)
Title: Bidirectional optically powered signal transmission device
Inventor: TSUJI NOBUHIKO
IPC: H04B10/00
Filed: 1996-05-30
Abstract: The signal transmission device has two optical transmitter stations. The first transmission station (10) has a first device (31,32,33) for transmitting a signal light beam via an optical transmission path (41a) to the second transmission station (20,30). It also receives a second signal light beam via the optical transmission path, from the second transmitter station.  The second station has a second device (22,23,29) for transmitting a second signal light beam via the optical transmission path to the first station and for receiving the first signal light beam from the first transmission station. The second transmission station also has a fourth device (26) to receive the power light beam. This converts the power light beam into electric power to operate the second transmission station. The first and second signal light beams have different wavelengths.

Title: Drafting frame for spinning provides two well compacted slivers
Inventor: STALDER HERBERT DR
IPC: D01H5/74
Filed: 1996-06-14
Abstract: A spinning machine has multi-stage drafting frame(s) fed from one or two roving reels (12), alternatively sliver cans, where one of the outlet rollers (25, 26) is a suction device (25) with a perforated region (35) which, over a path section, provides a co-travelling guide surface for two adjacent draw frame slivers (22, 22').   A condenser stage is thus formed where the slivers, now finally drafted but not yet twisted, are condensed or bunched into compact fibre cords (22), i.e. not more than 1.5 and preferably less than 1 mm thick and two connected spinning devices (17) impart final twist. Two suction zones (33, 33') are formed a distance apart along and, as defined by a screen, transverse to the circumferential path section within the perforated region.   In the direction the suction device moves at least one of a zone's boundaries is unaligned with that direction and each zone drives one of the slivers circumferentially. The zones converge at least in the middle towards each other from any circumferential point (46) where two separate slivers are laid down and in the direction sliver is fed.

Title: Sieve drum washer cleaning-off finer material from filtration media comprising, e.g., sand or gravel
Inventor: SCHWENK RUEDIGER
IPC: B07B1/24
Filed: 1996-07-03
Abstract: The sieve drum washer cleans and separates mixtures of water and solids, and, in particular, rinses off filtration material comprising, e.g., sand or gravel which includes absorbed contaminants from potable water and service water purification. The drum is internally-sprayed and rotates about its horizontal axis, carried on rollers. It has a charging unit leading into it, and a rotary drive. New features include the charging device which reaches almost to the far, closed end of the drum. This is a channel (20), upwardly open over part of its length. On the inner wall of the sieve drum (7) there is a hollow spiral (8), conveying material over the washed sieve. Along the entire internal length of the drum, a row of downwardly directed spray-washing nozzles (23) is fitted. An enlarging collar (17) projecting out from the open end of the casing ejects the washed bulk material. Flanges (9, 10) at either end of the drum lie against axially-locating guide rollers (11, 12). Drive (5) is applied at the closed end of the drum, through a flexible coupling (6). A row of spray nozzles (27) located above the drum back wash the sieve perforations. Charging channel (20) and internal wash nozzle tube (24) are fastened to a traverse (25), which is detachable at the open end of the drum. The drum casing is made of curved, perforated- or slotted sheet, without reinforcements or bracing.
Patent DE-19632400-A1 (DE)

IPC: B25G1/04
Filed: 1996-08-10
Abstract: The invention relates to mutually telescopable components (3, 5), e.g. pipes, especially vacuum cleaner handle sections, in which selected positions can be engaged by means of a locking component (8), where in addition the locking component (8) has a pressure-operable engagement knob (10) and an engagement projection (13) on the engagement knob (10), where said engagement knob (10) is open for operation on a first telescopic section (5) and the engagement projection (13) engages in a second telescopic section (3). To provide an improved engagement component for telescopic sections, especially one of minimum  structural height and with a minimum of parts, it is proposed that the engagement knob (10) project from the outer telescopic section (5) for operation and work together with the inner telescopic section (3) via a rocker-like support.

Title: Ultrasonic method of flow measurement for fluids
Inventor: POL RONALD VAN DER DIPL ING
IPC: G01S15/58
Filed: 1996-08-21
Abstract: The method employs a measurement tube (1) on which are positioned at least two ultrasonic transducers (4, 5) which beam to and receive from at least one measurement path (3), ultrasonic pulses (2). From the echo time of the pulses the mean flow speed of the medium is determined and from that the flow. From a Doppler shift of the ultrasonic pulses (8) reflected along the measurement path by the inhomogeneities (7) contained in the medium and the echo time of these pulses a flow profile of the medium is determined. From the profile a correction is applied to the value of the mean flow speed.

Title: SECAM L and SECAM BG transmission norm recognition method
Inventor: MOLL HOLGER
IPC: H04N9/64
Filed: 1997-04-24
Abstract: The method involves multiplying a colour synchronisation signal of a colour-under colour signal with itself. One of the colour synchronisation signals is phase shifted by 90 degrees if it has a frequency above the frequency of a red colour synchronisation signal of a SECAM BG signal in colour-under frequency position. A phase shift of minus 90 degrees is carried out if the frequency is below the frequency of a blue colour synchronisation signal of a SECAM BG signal in colour-under frequency position.  The product is low pass filtered, rectified, inverted alternating in display lines and integrated. The integrated signal is coupled to a first capacitance whose charge state indexes a colour signal of the SECAM BG transmission norm. The low pass filtered signal is integrated and the integrated signal is coupled to a second capacitance whose charge state indexes a colour signal of the SECAM L transmission norm.

Title: Continually-operated looping machine for traditional looped pretzel rolls
Inventor: CORONGIU ROLAND DIPL ING
IPC: A21C3/08
Filed: 1997-04-24
Abstract: An assembly for converting pre-portioned pieces of bakery dough into traditional looped pretzel rolls comprises a first narrow conveyer belt and a second wider conveyer belt arranged at low-level. A looping station is located beneath the first belt, which captures and twists the two sides of the hanging dough. The resulting knot is secured and prevented from untwisting by a unit consisting of two rotating belts, relieving the dough side-arms of weight above the twisted section. The two hanging arms come to rest on the second belt, followed by the main body of the pretzel.  The novelty is that the release of the main body of the pretzel is synchronised by a blocking element which lifts the body and releases it at the right moment.
